5.1 Product Specifications
The MVI56E Modbus TCP/IP Multi-Client Enhanced Communications Module for
Remote Chassis allows Rockwell Automation
®
ControlLogix
®
Programmable
Automation Controllers (PACs) to interface easily with multiple Modbus TCP/IP
server-compatible instruments and devices. The multi-Client module improves
performance when controlling multiple servers on a Modbus TCP/IP network, by
supporting up to 30 Clients.
MVI56E enhancements include configuration and management through the
module’s Ethernet port, and CIPconnect
®
technology for bridging though
ControlNet™ and EtherNet/IP™ networks.
This module uses a small I/O data image for transfer of data between the module
and the ControlLogix processor, making it ideal for ControlNet or Ethernet
applications with the module in a remote rack.
